A hard-disk term that describes a method of arranging disk sectors to compensate for relatively slow computers. Spreads sectors apart instead of arranging them consecutively. For example, 3:1 interleaving means your system reads one out of every three tracks on one rotation. The time required for the extra spin lets the read/write head catch up with the disk drive, which might otherwise outrun the head's ability to read the data. Thanks to track buffering and the speed of today's PCs, interleaving is obsolete. Look for a "1:1 interleaving," which indicates a noninterleaved drive.
The alternate placement of audio and video data with computer data to permit faster access and closer synchronization of sound to onscreen displays. Interleaving is defined under Green Book.
Distributing access order in other fashion than a straight access. Electronics of the older drives was not fast enough to read sectors one after another. Therefore, sector renumbering was introduced creating artificial delays in the stream of incoming data. Interleaving factor 3:1 meant that two sectors will be skipped before reading of the next one. Modern drives have electronics capable of handling the data generated by the drive data stream, making interleaving obsolete.
The process of assigning consecutive physical memory addresses alternately between two memory controllers to increase the effective transfer rate.
Physical location of sectors are different to logical location - logically sectors are sequential whereas they will be physically separated
A process of scrambling the order of symbols to be transmitted over a channel in such a way that, when they are descrambled (at the receiver), any burst of channel errors will be spread out in time and thus appear as random errors to the decoder.
A method of reducing errors in digital data, interleaving distributes and intermingles the consecutive bits or words of data, spreading them over a wider area on the storage media, and scattering potential errors. This helps protect against consecutive errors when the data is read back. A variety of different schemes for interleaving are used for CD, DAT and other medias, but as an example, on DAT one method uses one record head to write the right channel's even samples and the left's odd samples, while the other head writes the left channel's even samples, and the right's odd samples. In the case of a burst error (such as those caused by a dirty head), only half of either channel's samples will be affected, allowing interpolation to conceal the lost data. (See also DJzone " Linear Interpolation")
The process of rearranging data in time. Upon de-interleaving, errors in consecutive bits or words are distributed to a wider area to guard against consecutive errors in the storage media.
intermixing the video and audio data in the final file. Interleaving is required for proper playback of movies, because it allows the drive to read the file in a linear fashion and still receive the separate audio and video data as needed. QuickTime's standard interleave is one second of video followed by one second of audio for the first second of the movie, and a 1/2 second interleave throughout the remainder. AVI has several different interleave options, including interleaving each frame of video with the audio.
Interleaving is a method of ADSL delivery that increases the amount of error correction performed on your line by the DSLAM. Basically, it checks every single packet sent to or from the DSLAM to ensure that they are not corrupted. Interleaving may increase packet loss, as it will discard packets that are found containing errors, but will improve ping time for some customers.
The process of intermixing the video and audio data into one final file. Interleaving is required for proper playback of movies because it allows the drive to read the file in a linear fashion and still receive the separate audio and video data as needed.
Interleaving is a recording method that reduces data errors during playback. Instead of the file being written in a contiguous data stream, the data sectors are intermixed along the recording track. If a disc should have a smudge or scratch, the entire data file is generally recoverable because a smaller amount of the file data is affected. ISO 9660 - Issued by the International Standards Organization, its formal title is ISO 9660: Information Processing--Volume and File Structure of CD-ROM for Information Exchange (1988). This multi-platform logical structure has been the key standard for the growth and worldwide acceptance of CD-ROM as a publishing and information distribution media and, since then, as the basic format structure for other implementations of CD-ROM in the computer arena.
A physical process rendering data more immune to burst errors whereby bytes from one input group are assigned to multiple output groups upon recording using a precisely defined method. De-interleaving during reading reverses the interleaving process, assembling data while dispersing read errors (also see CIRC.) Or, a logical process of recording multiple files whereby each file is divided into extents, each containing a fixed number of blocks, that are recorded in a predetermined pattern having a fixed spacing between extents, and are alternated with extents of other files. Padding extents may be utilized if files are not of the same size.
Interleaving is a tunable aspect of DMT/ADSL line encoding. It essential controls the 'interleaving' of bits in the transmission, and is used as a form of error correction. As interleaving increases, so does stability of marginal lines. It also increases latency.
Interpolate Intersymbol Interference
Refers to the way sectors on a hard drive or disk are arranged. It can also refer to the way memory such as DRAM is organized. In both cases its purpose is to improve efficiency.
A technique for storing data more efficiently by arranging parts of one sequence of data so they alternate with parts of another sequence of the same data. When the data is retrieved, the system puts the sequence back together again.
Interleaving in computer science is a way to arrange data in a non-contiguous way in order to increase performance.
